Viscoelastic friction type energy dissipation self-resetting buckling-restrained brace

Abstract

The invention provides a viscoelastic friction type energy dissipation self-resetting buckling-restrained brace. The viscoelastic friction type energy dissipation self-resetting buckling-restrained brace comprises an upper fixing cylinder, a lower fixing cylinder, fixing guide plates, a piston rod, a fixing end plate, springs, a first viscoelastic energy dissipation assembly, a second viscoelasticenergy dissipation assembly, first friction structures and second friction structures. Both ends of the fixing guide plates are separately inserted and fixed into the upper fixing cylinder and the lower fixing cylinder. The piston rod is arranged between the interior of the upper fixing cylinder and the interior of the lower fixing cylinder. The first viscoelastic energy dissipation assembly andthe second viscoelastic energy dissipation assembly separately sleeve both ends of the piston rod. The springs are arranged between the first viscoelastic energy dissipation assembly and the second viscoelastic energy dissipation assembly. The first end of the piston rod limits the first viscoelastic energy dissipation assembly, and the fixing end plate limits the second viscoelastic energy dissipation assembly. The viscoelastic friction type energy dissipation self-resetting buckling-restrained brace has self-resetting capability, can be automatically adjusted according to the brace force deformation characteristics to prevent damage to the internal components of the brace, and has stable and efficient energy dissipation capability.

Description

Technical field [0001] The invention relates to the technical field of earthquake resistance and shock absorption, in particular to a viscoelastic friction type energy-consuming self-resetting anti-buckling support. Background technique [0002] Structure passive vibration reduction control technology, as a vibration control method in the field of civil engineering, has achieved fruitful results in both theoretical research and practical engineering applications. The basic principle of structure passive damping control technology is to install damping energy-consuming devices in the building structure, and dissipate the energy input into the building through the damping energy-consuming devices to reduce the structural dynamic response. The passive damping control technology of structure has the characteristics of low cost, simple structure, does not require external energy, is easy to maintain, and has a low probability of failure in the event of earthquakes and other disasters....
